This test method defines the procedure for performing validation checks of the measurements of pavement surface macro-texture determined using a laser profilometer, by comparing them to the measurements from a static or manual reference device.

It is preferable that the surface texture measurements made by the laser profilometer are validated against an objective measuring device that is not influenced by human error. However, if access to such a device is not possible comparisons can be made against manual sand patch measurements.

This test method is one of two alternative validation methods required by Austroads Test Method AG:AM/T013. The other validation method is Austroads Test Method AG:AM/T015.
